Polypyrrole Conductive Polymer-Coated Carbon Nanotube
At DOE's Environmental Molecular Sciences Laboratory, scientists study polypyrrole conductive polymer-coated carbon nanotubes grown on a carbon fiber. These nanotubes could be used as an electrochemically switched ion exchange electrode for water purification. This work is part of efforts to obtain a high-surface-area electrode for efficient water purification.
